Description
Technical Field
The invention relates to the technical field of ships, in particular to a perforated structure of a platform in an isolation empty cabin of a stainless steel cargo ship.
Background
The liquid cargo ship is usually provided with an isolation empty cabin between two or more than two left and right liquid cabins to ensure the safety when different kinds of liquid cargo are loaded. The isolated empty chamber consists of two longitudinal bulkheads and two plate-shaped transverse bulkheads. The liquid tank boundary adopts a horizontal groove type transverse bulkhead.
Corresponding to the junction of the horizontal channel-type transverse bulkhead and the longitudinal bulkhead of the liquid tank, a rigid perforated plate is usually added in the isolated empty tank to reinforce the transverse bulkhead of the isolated empty tank. In the isolated cavity, if a platform is arranged near the rigid perforated plate, the rigid perforated plate and the rib plates at the platform have very large stress due to stress concentration.
In order to reduce the stress, the prior art firstly ensures the continuity of the platform, breaks the transverse bulkhead in the isolation cabin, and improves the structural strength by increasing the plate thickness of the transverse bulkhead at the position, in particular to locally insert thick plates. In this way, the stainless steel plate thickness of the transverse bulkhead needs to be increased greatly, and the plate thickness difference from the original base plate thickness of the transverse bulkhead is large.
According to the regulations of relevant ship regulations, the welding requirements for stainless steel plates are as follows: the thickness difference between adjacent stainless steel plates is not more than 4 mm. In practice, the thickness difference between the inserted thick plate and the base plate is usually much larger than 4mm, so that one or more circles of transition plates are required to be added between the inserted thick plate and the base plate. While stainless steel is expensive. The existing method not only increases the weight and the production cost of the structure, but also increases the workload of production and construction.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects in the prior art and provide a perforated structure of a platform in an isolation empty tank of a stainless steel cargo ship.
The invention solves the technical problems through the following technical scheme:
a platform open pore structure in an isolation empty cabin of a stainless steel liquid cargo ship is arranged in the stainless steel liquid cargo ship, the stainless steel liquid cargo ship is provided with two longitudinal bulkheads, the outer side of each longitudinal bulkhead is connected with a plurality of horizontal groove-shaped transverse bulkheads, and the longitudinal bulkheads and the horizontal groove-shaped transverse bulkheads form a liquid cabin; a plate-shaped transverse bulkhead is arranged between the two longitudinal bulkheads at the position corresponding to the horizontal trough-shaped bulkhead; the plate-shaped transverse bulkhead and the longitudinal bulkhead enclose a plurality of isolated empty cabins; a platform and a rigid perforated plate are arranged in the isolated empty cabin, and the perforated plate is arranged at the connecting part of the horizontal groove type transverse cabin wall and the longitudinal cabin wall corresponding to the liquid cabin; the platform is close to the perforated plate; the platform extends on two sides of the plate-type transverse bulkhead; the platform is disconnected at the plate-type transverse bulkhead, and two sides of the plate-type transverse bulkhead are respectively provided with a platform plate; the platform plate is welded to the plate-type transverse bulkhead and the longitudinal bulkhead simultaneously; the platform plate is provided with an arc-shaped through hole at the intersection of the plate-shaped transverse bulkhead and the longitudinal bulkhead; the radius of the arc-shaped through hole is not less than 50mm and not more than 200 mm.
Preferably, the deck plate is fusion welded to the plate-shaped transverse bulkhead. The stability of the structure of the platform itself can be ensured by means of deep fusion welding.
Preferably, the arc-shaped through hole is in the shape of a quarter circle; the center of the quarter circle is positioned on the intersecting line of the plate-type transverse bulkhead and the longitudinal bulkhead. According to the finite element method calculation, compared with other shapes, the shape of the arc through hole is formed by taking the quarter circle, and the stress at the connecting part of the horizontal groove type transverse bulkhead and the longitudinal bulkhead is the smallest.
Preferably, the radius of the arc-shaped through hole is 150 mm. The arc-shaped through hole with the size has the smallest stress at the connecting part of the horizontal groove-shaped transverse bulkhead and the longitudinal bulkhead through calculation of a finite element method.
Preferably, the platform plate is fixedly connected with the two longitudinal bulkheads simultaneously; the number of the arc-shaped through holes on each platform plate is two. The finite element method calculation shows that the stress at the connecting part of the horizontal groove type transverse bulkhead and the longitudinal bulkhead can be further reduced by arranging the two arc-shaped through holes.
The positive progress effects of the invention are as follows: the invention effectively reduces the stress at the connecting part of the horizontal groove type transverse bulkhead and the longitudinal bulkhead; and the thickness difference between the inserted thick plate and the base plate can be controlled within 4 mm. Therefore, a transition plate is not required to be added between the inserted thick plate and the foundation plate, so that the structural weight and the production cost can be reduced, and the workload of production construction can be reduced.
